Front panel procedure: (P-band waveguide example)

1.Prior to modifying or generating a cal kit, store one or both of the cal kits in the 8510’s non- volatile memory to a disk.

2.Select CAL menu, MORE.

3.Prepare to modify cal kit 2: press MODIFY 2.

4.To define a standard: press DEFINE STANDARD.

5.Enable standard no. 1 to be modified: press 1, X1.

6.Select standard type: SHORT.

7.Specify an offset: SPECIFY OFFSETS.

8.Enter the delay from Table 1: OFFSET DELAY, 0.0108309, ns.

9.Enter the loss from Table 1: OFFSET LOSS, 0, X1.

10.Enter the Z0 from Table 1: OFFSET Z0, 50, X1.

11.Enter the lower cutoff frequency: MINIMUM FREQUENCY, 9.487 GHz.

12.Enter the upper frequency: MAXIMUM FRE- QUENCY, 18.97 GHz.

13.Select WAVEGUIDE.

14.Prepare to label the new standard: PRIOR MENU, LABEL STANDARD, ERASE TITLE.

15.Enter PSHORT 1 by using the knob, SELECT LETTER soft key and SPACE soft key.

16.Complete the title entry by pressing TITLE DONE.

17.Complete the standard modification by press- ing STANDARD DONE (DEFINED).

Standard #1 has now been defined for a 1/8 λ P-band waveguide offset short. To define the remaining standards, refer to Table 1 and repeat steps 4 -17. To define standard #3, a matched load, specify “fixed.”

The front panel procedure to implement the class assignments of Table 2 for the P-band waveguide cal kit are as follows:

1.Prepare to specify a class: SPECIFY CLASS.

2.Select standard class S11A.

3.Inform the 8510 to use standard no. 1 for the S11A class of calibration: l, X1, CLASS DONE (SPECIFIED).
